Abstract RU 2244082 C2

FIELD: building, particularly swimming pool structures.

SUBSTANCE: pool has overflow gutter divided by longitudinal water-impermeable partition into two chambers, namely settling chamber and water filtering chamber, along the full gutter length. Overflow gutter has lids provided with grids of V-shaped cross-sections arranged from lid inner surfaces. One grid side faces overflow gutter, another one faces pool bowl and is supported by curved part thereof on front wall of overflow gutter. Attached to perimeter of front gutter wall is inner edge of overflow "apron". Working "apron" part is located in plane of floating "mat" and cooperates with it and with V-shaped grid side facing gutter to prevent water entering into overflow gutter from returning into pool bowl. Another apron part freely hangs down and passes into settling chamber to divide setting chamber into two areas, namely ascending flow area and descending flow area and to protect main working part of overflow gutter from dirt ingress. Floating "mat" together with "apron" creates annular "dam" between overflow gutter and pool bowl due to their lifting together with each wave and pressing to corresponding side of V-shaped grid to maintain water level difference and to provide water circulation through purification system and returning thereof to pool bowl. Water self-purification intensity is increased as pool employment activity is increased. Filtering chamber includes filtering materials having small flow resistance. Filtering material may be formed of polyurethane foam members having differently sized opened pores and laid in layers. Polyurethane foam members are densely pressed one to another and to chamber walls and spaced from base to create drainage channel having pipeline connecting thereof with pool bowl.

EFFECT: reduced wave energy losses, possibility to protect working zone of overflow gutter against ingress of dirt, increase efficiency of water cleaning.
